    I am trying to supply 12v to 2 inch 7segment using microcontroller. I want to switch 12v supply by transistor. I used bc547 for that but did get? Can any body give me solution for switching 12v power supply using a microconroller.

    Microcontroller - Phiips 89V51RD2FN
    Oscillator - 11.0592

    used in my project.
